Well, the deed is done. Decided to shoot for 154F but, since I'm still dialing in my new larger Coleman Xtreme, came in a little low. Went ahead and added some boiling water and ended up at 156F (155F end of mash). Came pretty close on my volume (1+ quart extra) and OG (1.102). Pitched on top of the WY1728 cake from the earlier Irish Red and, wow, this evening come home from work to almost a gallon of muck in the blowoff container. Interesting brew day but I think I'm gonna like this one.
